Currently "-b" (backtrace) controls over what time window (backwards from now) the psd is computed and "-u" (update time) controls after what interval a new psd is computed. Old psds continually get more transparent and weaker in linewidth (== kind of fade out). Lots of values hard coded right now (frequ limits, number of old psds to keep, etc).

Uhm.. I think that image was created from the attached code.. |

Oh, right, command line parameters.. sorry, too long ago, no idea. You'll just have to try some values. |

I think this would really only be useful to debug certain electrical problems when setting up a station (e.g. getting rid of 50Hz hum, ...), i.e. when you have some sharp changes in the psd. For a monitor plot maybe some of the new PPSD plots could maybe be plugged into seedlink plotter, see obspy/obspy#1327. Those would be more consistent with the time axis of the normal seedlink plotter.. |
